Patented Sept. 27, 1932 UNITED STATES JAMES w. KENNEDY; or cnnromonjro mnn'ron I Application filed October 7,1930. Serial No. 487,042.

This invention relates to improvements in dilators and more particularly to an instrument for expanding the sphincter muscles in the rectum. The device can also be used in the treatment of constipation, piles, for poor circulation and other rectal diseases.

provide a device of this nature which will expand the sphincter muscles of the rectum without causing friction and without damage and pain.

Another object of the invention is to provide a device which will expand the rectum throughout its length in an even and uni form manner.

Still another object of the invention is to provide an instrument of this character consisting of a tube made from pliable material I 111g a'handle 8 at the top. The'function-o-f the rod is to expand the tube when inserted therein. Numeral 9 indicates a guard used and adapted to be inserted'in the rectum and a rod for expanding the wall of said tube.

Still a further object of the invention is to provide an instrument of this kind comprising a pliable tube adapted to fit in the rectum, a series of wire guides longitudinally disposed in said tube and a rod for forcing said wire guides and the wall of the tube outwardly.

A further object of the invention is to provide means to regulate the depth of insertion of the tube.

Other objects of the invention will appear as the disclosure progresses. The drawing is intended to merely indicate a possible embodiment of the invention. It is obvious that the actual needs of manufacture may necessii r v zable material so t can readily expand with tate certain mechanical changes. It is therefore not intended to limit the invention to the embodiment illustrated, but rather to define such limits in the appended claims.

For a more general understanding of the invention, attention is called to the drawing. In the drawing like reference characters denote like parts throughout the specification. Figure 1 is a sectional view of the dilator in operative position.

Figure 2 is a similar view as Figure 1 with the rod and adjusting guard removed.

Figure 3 is an enlarged section on line 3-3 of Figure 1.

' Figures 6, 7, and 8 show the different size rodswhich can be used with the instrument. The principal object of the invention is to p 7 numeral 1 designates the tube made from a Referring now to thedrawing'in detail,

is a section on line 4-4 o f Figsoft and" pliable materialsuch as rubber or .the like. 2 the wire guides, and-3 the circular guides run longitudinally in pad. The wire the tube and are embedded at the top-in the circular pad. as ate, while thelower ends 5, are free to swing. Underneath the circular pad 18 attached a sheet of soft sponge rubber 1.-

6 in order to avoid anydamage to the skin when the instrument is in use. i

Fittinginthe tube is, a solid rod 7 havwhere the rectumis comparatively shallow as in children. The guard is made from a set of longitudinally disposed wire 10 woven together atthe top, as at 11 andresiliently. fastened to, the bottom disk 12 as indicated at The operation of this device is as follows:

Thetube withlthe I'Od"7 removed .is first placed in the rectum. The rod is then inserted in the tube and as the rod' movesdownwardly the wall of the tube will expand and enlarge the membrane of the, rectum. .As stated heretoforethe tube is made from pliabout. Otherwise there would always be a sharp difference in the diameter of the tube. The portion of the tube which is filled up with,

the rod would naturally be larger in diameter while at the end of the rod there would be a marked restriction in the diameter of the tube.

In Figures 6, 7, and 8 is shown aseries of, mo

'said wires,

different diameter rods which can be used with the instrument. In stubborn case the smaller rod is used first and as the rectum is stretched the larger and large sizes can gradually be used. Thus the rectum can gradually be enlarged without causing pain. The guard 9 resiliently fits on the tube and expands and contracts withsame-and does not in any way hinder the operation of the device. H k V 7 It will thus be seen that I have"provided an efficient and simple device for the purpose specified. The wall of the rectum will inf'no way be subject to friction, --but only to diametric expansion. The soft rubber tube is slightly pointedat the 'end-soitcan'enter the rectum without causing an unpleasant-feeling on the part oftheipatient. 3

Having described my invention,-I" clai m: 1. In a device of'the class described, the

combination of: apliable'tube, of a-set of wire guides in said tube and length thereof, a pad at the top of said'tube, the tops of said wire guides fastened'to 'a'd while the lower ends of said: guides being running the full un'fasten'e'd and free to swingyand means to the wall ofsai'd tube diametrically. '2. 'In a device of the classdescribed,the

"combination of a pliable tube,"of aset of wire guides in said tube and running the full length thereof, a pad at the top 'ofsaid tube,

a sheet of soft 'resil-i'ent'materiahattached to the bottom face of saidfpad, the tops of said wire 'guides fastened to said pad while the lower ends of said-guidesjbeing unfastened and free to swing, and 'me'ans to expand the wall of said'tu'be' diametrically.

3. In a device of the class described, the combination oif a pliable tube, of 'a-set of wire guides in said tube and runningthe full 5 length thereof, ap'adat the 'topof saidtube, 'the tops of said wire 'guides fastened'to said pad while the lower ends of saidguides beifig unfastened and fr ee to'swingimeans to expand the wall of said tube diametrically, 'aguard frictionally engagingthe outer' sur- "face of the tube, said-"guard comprisin'g'aset of longitudinally spaced wires 'woventogether" at the top, a pad at the lower en'd'of 7 said wires being bentatan' angle at-the bottom ends and' fitting into holes in "said pad.

In testimony whereofI afiix my signature.
